Question

多播服务未向地址节的所有收件人提供所有“到”属性。

UserA将数据包发送给UserB和UserC

<message type="chat" to="multicast.example.com" id="">
  <addresses xmlns="http://jabber.org/protocol/address">
    <address type="to" jid="UserB@example.com"/>
    <address type="to" jid="UserC@example.com"/>
  </addresses>
  <body>One</body>
  <active xmlns="http://jabber.org/protocol/chatstates"/>
</message>

然而，UserB收到

<message xmlns="jabber:client" from="UserA@example.com/iPhone" to="UserB@example.com" type="chat" id="">
  <addresses xmlns="http://jabber.org/protocol/address">
    <address type="to" jid="UserB@example.com"/>
  </addresses>
  <body>One</body>
  <active xmlns="http://jabber.org/protocol/chatstates"/>
</message>

UserC收到

<message xmlns="jabber:client" from="UserA@example.com/iPhone" to="UserC@example.com" type="chat" id="">
  <addresses xmlns="http://jabber.org/protocol/address">
    <address type="to" jid="UserC@example.com"/>
  </addresses>
  <body>One</body>
  <active xmlns="http://jabber.org/protocol/chatstates"/>
</message>

因此，UserB和UserC在地址节中相互缺少'到'属性。

我使用ejabberd 16.01并使用https://docs.ejabberd.im/admin/guide/configuration/#modmulticast配置

尝试此更改。这很奇怪，因为这些线路自多年前就没有变化。也许这个bug在别的地方，这只是一个解决方法：

mod_multicast没有向接收者提供正确的地址节
